BY DIRECT AND MESNE ASSIGN- MEN'IS, TO WERNER FILM-PROTECTOR MANUFACTURING COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.

EMOLLIENT FOB. MOTION-PICTURE FILMS.

No Drawing.

To all whom it may concern.

Be it known that I, PAUL WERNER, a citizen of the United States, residin at the city of St. Louis, in the State of issouri, have invented certain new and useful Improvements in Emollients for Motion-Picture Films, of which the following is a specification.

This invention is a composition of matter especially designed for lubricating the edge or edges of celluloid or other films for motion pictures. It is useful, also, to soften celluloid or the like used in automobile cur-- tains'or elsewhere, and, if rubbed on glass in motor-vehicle Windshields or the like, will prevent rain adhering thereto.

It is customary for a row of perforations to be made in each motion picture film, which row extends from one end to the other of such film. These perforations are so spaced apart asto fit the projections on a s rocket wheel in a motion picture machine.

ach of the said perforations is rather close to its neighbor. Celluloid is so brittle and so easily torn and so easily dries and hardens' that tearing from one perforation to another is hard to avoid, and, moreover, when a film tears from one perforation to another, a crack isthereby started that is likely to extend a, considerable distance and ruin the film. It may cost thousands of dollars to produce the original film, and yet it may be destroyed and its usefulness ended by the splitting thereof along the line of the said perforations. The object of this invention is to obviate such danger of destruction of films, whether made of celluloid or any similar material.

The conditions are the same or substantially similar regardless of the material. This article is an emollient, and softens and keeps a soft the edge or edges where such perforations as above-mentioned are located.

This composition of matter is preferably made from the following ingredients in sub- Specification of Letters Patent.

Patented Sept. 28, 1920;.

Application filed April 7, 1919. Serial No. 288,420.

It will be observed (1 lb.) avoirdupois.

Besides the above-mentioned use of the emollient the subject-matter of this invention, it may be used, also,,as a humidifier in a motion-picture film safe or vault. After perforated receptacles containing this composition of matter have been placed at intervals between the rolls of films within a motion-picture safe or vault, enough moisture is given off from the masses of this material to moisten and keep pliable the films stored within such vault. It is characteristic of motion-picture films to dry and become brittle and thereupon they crack and break upon being handled. However, it has been found by experiment that motion-picture films stored in a vault provided with a plurality of receptacles containing this composition of matter will not become dry and brittle, but remain moist and pliable. Old films already dried out will respond to the effect of this material if placed in proximity thereto (such as in a safe provided with this material) and will become softened and fit for further display. Receptacles containing this composition may, also, be placed in the boxes or other receptacles in which films are packed for shipment or transportation of motion-picture films, for the purpose of preventing said films from becoming dry and brittle.

It is to be understood that the quantities or proportions of the herein-named ingredients may be more or less changed or varied within the scope of the following claims.

ll claim:

1. An emollient composed of wax, -camphor,'and fatty material.

2. An emollient composed of paraffin wax, camphor, and fatty material.

3. An emollient composed of beeswax. paraflin wax, camphor, stearic acid, and tallow.

4.. An emollient composed substantially of one-half ounce oz.) beeswax, six and onehalf ounces (6% oz.) parafiin wax, one ounce (1 oz.) pulverized camphor, one-half ounce (1} oz.) stearic acid, and sevenand one-half ounces (7% oz.) tallow.

In testimony whereof I hereunto aflix my signature.
